Degradation of carbofuran in aqueous solution by ultrasound and Fenton processes: Effect of system parameters and kinetic study

Effect of ultrasonic treatment on the degradation and inhibition cancer cell lines of polysaccharides from Porphyra yezoensis

“…It has been found that the maximum extent of degradation is observed at 2.0% H 2 O 2 . This might be due to the increase in OH radical formation when H 2 O 2 is first added, but at higher H 2 O 2 concentrations OH might be consumed by various mechanisms, including the scavenging effects of H 2 O 2 and the recombination of OH radical (Ma, Sung, & Lin, 2010).…”

Removal of herbicide 2,4-D using conductive-diamond sono-electrochemical oxidation

“…This powerful oxidant is responsible for harsh oxidation conditions [21][22][23][24][25]. Ultrasound irradiation combined with electro-oxidation can be very effective for the removal of different organic pollutants such as dyes [26][27][28], phenolic compounds [29][30][31], organo-chlorinated species [32], pharmaceutical products [23,33,34], phthalates [25,35] and pesticides [24,36]. Regarding pesticides, Bringas et al [24] evaluated the degradation kinetics of diuron using low-frequency ultrasound irradiation coupled to electrochemical oxidation with a boron-doped diamond anode.…”

Impacts of operating parameters on oxidation–reduction potential and pretreatment efficacy in the pretreatment of printing and dyeing wastewater by Fenton process

“…The shorter reaction time and faster degradation rate imply a lower capital cost than other advanced oxidation processes [15][16][17]. In addition, the Fenton's reagent is relatively cheap, easy to handle compared with other advanced oxidation processes [18], reacts well with organic compounds and does not produce toxic compounds during oxidation [19], Fenton process has been widely applied to treat various types of industrial wastewater [14,[20][21][22]17]. The investigators have found that Fenton oxidation is effective in decolorizing and degrading organic compounds of the wastewater that contains various types of dyes [23][24][25][26].…”
